Abstract
Description
- The present invention relates to a machine and a method for producing substantially cylindrical articles of the tobacco processing industry.
- In the tobacco processing industry, it is known to produce multi-segment filter tips provided with different materials.
- The patent application bearing publication number US2014/2061470 describes the production of a cylindrical article comprising a filter segment, a segment of granular material and a segment of tobacco. To obtain this cylindrical article, a band of flexible material is wrapped around the filter segment so as to obtain a cup-like form, which is filled with the granular material. At this point, the segment of tobacco is placed on top and is only subsequently connected to the remaining parts of the article by rolling a sheet of paper material around the segment of tobacco and the segment of filtering material. The above-described operations are performed while keeping everything vertical.
- That proposed by patent application US2014/2061470 has several drawbacks, from which we cite the fact that production is relatively slow and of low quality.
- It is an object of the present invention to provide a machine and a method that enable at least partially overcoming the drawbacks of the known art and, at the same time, are of easy and inexpensive implementation.
- According to the present invention, a method is provided for producing substantially cylindrical articles of the tobacco processing industry according to that set forth in the independent claim below and, preferably, in any of the dependent claims directly or indirectly dependent on the above-mentioned independent claim.
- According to a further aspect of the present invention, a machine is provided for producing substantially cylindrical articles of the tobacco processing industry, as described below. In particular, the machine is designed to implement the above-mentioned method.
- The present invention will now be described with reference to the accompanying drawings, which illustrate a non-limitative embodiment, in which:

Thanks to the above-mentioned handling system, eachnozzle 40 is opened when the nozzle is placed (at least partially) inside the open end. - In particular, the opening of each
nozzle 40 is achieved by a relative separating movement between thenozzle 40 and a respective blocking element 41 (of each insertion unit 38), located inside a feed channel 42 (of each insertion unit 38) of the loose material (FIG. 16 ). More precisely, the handling system is designed to bring eachnozzle 40 toward the intermediate element 2 (in particular, downwards) so as to move thenozzle 40 away from the respective blocking element and therefore open thenozzle 40 and allow the passage of the loose material through thenozzle 40. In practice, theinsertion device 11 is designed to keep theblocking element 41 vertically fixed. - As a consequence of insertion of the loose material in each
intermediate element 9, the respectiveintermediate element 12 is obtained. - The above-mentioned handling system is designed to move each
nozzle 40 away from the respectiveintermediate element 12 at the exit station B. The upward movement of thenozzle 40 causes the blockingelement 41 to engage again and therefore close thenozzle 40. - Usually, a
hopper 43, designed to house the loose material and feed eachfeed channel 42, is located above theinsertion units 38. - According to specific embodiments (such as that shown), a conveyor drum (two in this specific case) 33′ is provided to carry the
intermediate elements 9 from thedrum 33 to theinsertion device 11. - According to an embodiment that is not shown, the

According to some embodiments, the openingassembly 54 comprises a plurality ofsuction openings 55 arranged (in a ring) at eachinsertion outlet 50. In this way, the risks of damaging thesheet 7 are reduced. - Advantageously, each
insertion unit 48 comprises a deformation device to reduce the size (in particular, laterally) ofportion 4 during insertion of saidportion 4 into theopen end 10. According to some embodiments, the above-mentioned deformation device comprises asection 56 of theinsertion channel 51 having a width (in particular, a cross-section) less than the width (in particular, the cross-section) ofportion 4. In particular, thesection 56 is tapered towards theinsertion outlet 50. Advantageously, thesection 56 is arranged immediately (i.e. without the interposition of further sections) upstream of (in particular, above) theinsertion outlet 50. - According to the embodiment shown, the
portions 4 are fed to theinsertion device 13 through aconduit 49′ connected to a hopper (of a type in itself known and not shown). - Usually, a
conveyor system 57 is arranged downstream of theinsertion device 11 for the transfer of the substantiallycylindrical article 2 obtained to further processing units (of known type and not shown). According to the embodiment shown, theconveyor system 57 is designed to carry the substantially cylindrical article substantially horizontally. More precisely (for this purpose), theconveyor system 57 comprises a truncated cone shapeddrum 58. - According to alternative embodiments, the
